Hi, Thanks for using HCM.
Since you are trying conceive and no birth control pills, missed periods may be due to
pregnancy. But since your UPT is negative, you can get blood
HCG level to confirm/rule out pregnancy. Start taking
folic acid tablets if not started.
The other possibility for missed period, other than pregnancy is
hormonal imbalance or any infection. You can get done USG abdomen and pelvis and speculum examination if your blood HCG level in non pregnant stage or intra vaginal scan if HCG level is raised to correctly diagnose the cause.
Based on examination and investigation we can give correct treatment.
Keep genital area dry and clean. Maintain good hygiene. Hope this answered your question. Consult your doctor for further management.
Feel free to ask me if you have any further queries or doubts and I shall be glad to help you out.
Wish you good health. Take care.
Regards
